PROBLEM TO BE SOLVED: To provide a mold structure for effectively preventing occurrence of a casting flash. SOLUTION: A die casting mold is constituted with a mold main body 1 which is not quenched, one cavity mold 2 and the other cavity mold 3 which are quenched. A tip 6 of a casting pin 5 is projected from the cavity mold 2, and is closely pressed to a butt part 11 of the other cavity mold 3 with a coil spring 8. The coil spring 8 is stronger than a conventional one, and one end of the spring 8 abuts on a thick diameter part 14 and the other end abuts on a plate-like part 16 of a spring receiving member 15 which is quenched and surface-treated. Thereby, the coil spring 8 is nipped between the mold main body 1 and the cavity mold 2, and the mold main body 1 and the cavity mold 2 are integrally fastened with a bolt 18. By dosing so, the coil spring 8 can be simultaneously compressed at an extent to obtain a spring elasticity required for casting flash prevention.
